Effect of pH on the adsorption efficiency of CR over the EG@MnFe2O4 (a) and MnFe2O4 (b) materials. Experimental conditions included adsorbent dose of 0.5 g/L, solution volume of 100 mL, and dye concentration of 60 mg/L at various pH (2–12). Experiments were run at room temperature (25°C) during 210 min.
